Ginger Oil Nanoemulsion Formulation Augments Its Antiproliferative Effect in Ehrlich Solid Tumor Model

Area of Science:

• Pharmacology
• Nanotechnology
• Oncology

Background:

• Breast cancer is a prevalent disease with limited treatment efficacy.
• Ginger oil possesses anti-cancer and antioxidant properties but suffers from poor oral bioavailability.
• Improving ginger oil's absorption is crucial for enhancing its therapeutic potential.

Purpose of the Study:

• To develop and evaluate a nanoemulsion of ginger oil for enhanced oral bioavailability.
• To assess the in vivo anti-cancer efficacy of the ginger oil nanoemulsion against breast cancer.
• To compare the therapeutic effects of nanoemulsified ginger oil with free ginger oil.

Main Methods:

• Ginger oil nanoemulsions were prepared using high-pressure homogenization with various surfactants.
• Formulations were characterized for droplet size, PDI, zeta potential, pH, viscosity, and stability.
• The anti-tumor activity was evaluated in vivo using the Ehrlich solid tumor (EST) model in mice.

Main Results:

• Nanoemulsion formulations exhibited favorable physicochemical properties, including small droplet size and good stability.
• Transmission Electron Microscopy (TEM) confirmed spherical morphology of the optimized nanoemulsion.
• Ginger oil nanoemulsion significantly reduced tumor volume and weight, extended lifespan, and improved organ function in tumor-bearing mice, outperforming free ginger oil.

Conclusions:

• Ginger oil nanoemulsion significantly enhances oral absorption and in vivo anti-cancer efficacy.
• Nano-formulation offers a promising strategy for improving the therapeutic outcomes of ginger oil in breast cancer treatment.
• This approach suggests potential for better clinical efficacy in breast cancer patients.
